I've been a TextMate user for a long time now and I'm still finding new things to do with it. Here recently I wanted to use the RubyAMP TextMate Bundle and was a little miffed to find that it was pointing to my OS X system ruby. The error message looked something like this when it went looking for my ruby/gems.

No such file to load -- appscript (LoadError) from

If you are like me and have been using passenger, then you may have run into an issue when working with rails edge. I mean the REAL rails edge on Git, not that fancy rake task which I think is still pointing to a subversion snapshot. Let me take an aside on how to freeze rails edge to a project that you are managing in Git. This method is akin to using svn:externals. As a cop out, here are 3 links that you should read to learn how.

• http://railsontherun.com/2008/4/16/freezing-rails-with-git
• http://woss.name/2008/04/09/using-git-submodules-to-track-vendorrails/
• http://git.or.cz/gitwiki/GitSubmoduleTutorial

OK... now that you know how to freeze the real rails edge to your git project, and if you have been using passenger, you may now have seen this error below. The basic problem is that passenger bypasses the work that the rails boot.rb does and in doing so, it only accounts for setting RAILS_ROOT during the ApplicationSpawner process and not the FrameworkSpawner process. In the latest rails, ActionPack is now relying on RAILS_ROOT to be set by calling Rails.root (shortcut method to that constant) when loading. So my fix was to add the RAILS_ROOT to the FrameworkSpawner class.

Framework that failed to load: Vendor directory: /Users/foo/project/vendor/rails 
Error message: Anonymous modules have no name to be referenced by 
Exception class: ArgumentError

• Here is the Passenger Ticket
• The official Passenger change set that fixed this issue.

Well this is working out well so far. I'm really liking the Passenger (mod_rails for Apache) extension. Right now I have this Mephisto site running it and it seems to be doing really well. Also, most people do not do this, but I run a full development stack Apache/MongrelCluster to mimic production boxes the best way I can. Now I am running mod_rails on all my development hosts.

Some Things I Like

• I do not have to fuss with OS X launchd startup scripts for my mongrels, just Apache.
• Typically in a high volume site that runs mongrel behind an Apache proxy balancer, will get a large timeout and proxy error even if the mongrels are immediately available. Passenger has a nice way to restart the app, just touch the tmp/restart.txt file.

Some Things I'm Waiting For

• The RailsEnv can not be set per virtual host. You have to set RAILS_ENV = 'development' in each app if you want to run mixed virtual hosts with different environments.
• Normally I would pass environment variables to the console when issuing mongrel cluster starts. I would really love to see Passenger support apache environment variables.

Here is how to get a playlist of sounds that will be hooked to both your autotest :red and :green callbacks. Basically this gives you a folder of sounds that are played one after another, in a loop, as your tests pass or fail. See this move below for a quick example.

I just had an issue pop up today that seemed to be an issue for a few others. It seemed that all of a sudden that my autotest was stuck in an infinite loop after a failure or error. At first I thought it was related to some additions to my ~/.autotest file but after commenting out the whole lot of additions there, I realized it was something else. Here was my fix. Basically I think these errors are always related to a file that has changed during your test run. Now we just have to find out what that files are. Here are the steps I took to find out.

OK, so you want to keep your code placement REALLY organized. You have read about my persnicketyness and now you want to practice the best in concern placement and keep those controllers of yours really slim. Like me, you may want to try and keep controller feature additions to very specific one liners of code. Organizing your controller code to do just that with ActiveRecord models or even your own custom classes is a pretty easy task, but how do you keep things simple when dealing with controller actions that have to send email AND you want that single email link of code to be responsible for everything in it's own encapsulated way.

My MacBook is about a year old now and I've read in quite a few places that they could be upgraded to around 3.3GB of memory for this specific model. Unlike the latest MacBook which can "as advertised" accommodate 4GB of memory, the theory was that the Santa Rosa chipset can address all 4GB. It could very well be that technically my MacBook is only using ~3.3GB of that memory but the performance has been significant for a very cheap stick of RAM. I highly recommend Crucial.

I think this upgrade will have to hold me for some time. In general it has really helped my uptime. Odd as that is I think working with only 2GB of memory caused a lot of IO swap and memory corruption. Especially when stopping and starting so many different mongrels for local Rails development. As of this writing I have not found an issue that I have had to reboot for... uptime 10 days and going strong.

To keep my uptime going strong, I just purchased an app called iFreeMem today after reading about it on TUAW. Because I use PhotoShop ever now and then it really helped having this utility free up some memory that it would not release. So far it is working great!
